SEPARABLE JOI'IRNAI. BOX.

Application filed April y2,

The present invention relates to separable journal boxes. l

More particularly the present invention relates to journal boxes such as are used in connection with railroad trucks. The side trames ol railroad trucks have commonly been made with the journal boxes thereof integral with said side trames. ln many cases it. is convenient, however, to have the journal lboxes separable from the side trames. An object of the present invention is to provide a construction whereby such separability may be provided without danger ot accidental disengagement oiE the journal boxes from the side iii-ames.

further object is to provide a simple structure which is sturdy and safe and which facilitates the removal of the car wheels when such removal is desired.

'A further object is to provide a separable journal box which is well adapted to meet the needs ot commercial service.

Further objects will appear as the description proceeds.

Referring to the drawings- Figure l is a view in side elevation of a side trame having separable journal boxes mounted in cooperative relationship therewith, which side trame and journalboxes embody the principles of the present invention;

Figure 2 is a sectional view taken along the plane indicatedeby the arrows 2 2 of Figure l;

Figure 3 is a sectional view taken along the plane indicated by the arrows SW3 of Figure l;

Figure 4 is a view partly in section showing the interlocking connection between the side trame and the improved journal box;

Figure is a sectional view taken along the plane indicated by the yarrows 5fof Figure 4;

Figure 6 is a bottom plan view of a portion of one of the side frames with the journal box removed therefrom;

Figure 6 is a view similar to Figure 6 but showing a corresponding portion of the side frame on the opposite side of the truck; and

Figure 7 is a sectional view taken along the car axle illustrating` the parts in intermediate position when the journal box is being separated from the side frame;

Referring rst to Figures l and 2, the

spring plank and 'the bolster is omitted tor purposes oi2 clarity. No novelty is claimed for the bolster lf-l, but it may be explainedv briefly that said bolster may have shoulders lG-l6 which cooperate with the side frames llll to aid in holding saidside trames in Ispaced relationship with oneanother. The

spring plank l also serves to hold the side .trames lO-l0 in proper spaced relationship, and for this purpose said spring plank is provided adjacent to each of its extremities with apertures indicated by the numerals l'7-l 7, which receive lugs 18-18 on the side 'trames for holding' said side frames square with one another. Y

The numeral i9 indicates one of the car axles. Said axle*I is provided with the shoulder and the collar 2l', which receive between them the brass 22. Mounted upon the brass 22 is the usual wedge 23, which under service conditions supports the journal box 13. The journal box may beprovided on the interior thereof with the lug 24 for preventing the' accidental displacement oft the wedge 23. The upper portion of the journal box i3 is provided with the spaced gibs 25-25, which under normal conditions receive between them the corresponding porn tion ot' the side frame l0.

As best shown in Figures 4 and 7, that portion oT each of the side trames 10' which lies above the journal boxes is in the formfot' a box section, which box section is indicated bythe numeral'Qt. The bottom wall 2T of cach ol said box sections is provided withl a Tshaped slot-best illustrated in Fgur'e, said T-shaped slot comprising thev aperture 28 arranged longitudinally of' the corresponding side ramelOand' the aperture 29 arranged at right angles 'to the aperture A2S. Projecting upwardly from the top of each of the journal boxes 13 is a projection 30 of lshaped conformation. the head jot said T-shaped conformation beingl disposed longit-udinally ot' the corresponding side frame, which is to say-tigansvesely to the axis ot the corresponding car axle. The headportion 31 of the projection 30 and the lug pora spring plank for holding said side frames in spaced relationship with oneanother, a car axle, journal boxes at the tivo ends of said axle, brass and wedge means for preventing relative axial movement between said axle and said journal boxes when said brass and wedge are in their normal positions, said journal boxes being provided with gibs for receiving said side frames, each of said side frames and said journal boxes being provided With interiitting parts at the upper portions of said journal boxes, said interiitting parts being arranged to require movement of the two journal boxes at the ends of 'said axle in opposite directions to permit disengagement of said journal boxes iiroin said side frames, said interlitting parts in cooperation with each oil said journal boxes comprising a projection extendingr upwardly from the upper side of each journal box, which projection comprises an upwardly extending shank and a head portion, which head portion projects laterally from said shank in a direction parallel with the length of said side frames, each oit said side traines being provided with apertures in its under side for receiving` said projections, part or' each ot said apertures being of a size to receive its corresponding shank but too narrow to pass the corresponding head portion, another part of each of said apertures being` of a size to pass the corresponding head portion in a vertical movement of said side frame relative to said journal box.

4t. in combination, a side trame, a separable journal box cooperatively associated with said side frame, said box and said side 'traine having intertitting parts said interlitting parts comprising a projection mounted on the top of said journal box, said projection having an undercut head adapted to be disposed within the outline of said side frame, said side trame being provided With a shoulder adapted to abut said undercut head, said shoulder being defined by an aperture disposed laterally of said shoulder transversely of said frame, said aperture being of a size to pass said shouldered head.

5. In combination, a side trame and a separable journal box, said journal box having a projection extending upwardly 'from its upper side, Which projection comprises an upwardly extending shank and a head portion, which head portion projects laterally 'from said shank in a direction parallel with the length oi' said side frame, said side frame having an aperturein its under side, part of which aperture is of a size to receive said shank but too narrow to pass said head portion, another part of said aperture being of a size to pass said head portion in a verti-k cal` movement of said side fran'ie relative to said journal box, and gibs upon said journal box cooperating With said side frame to prevent movement of said journal box transversely of said side iframe When said side frame is in normal position upon said journal box.

6. ln combination, a pair ot side Aframes, and journal boxes cooperatively associated therewith, each of said journal boxes hav` ing a shouldered projection on its upper side, each of said side iframes being provided With shouldered apertures for receiving said projections, ithe walls orl said apertures being positioned to limit vertical movement of Said side frame relative to said project-ions when the corresponding journal box. is in one position laterally oi said side frame and each of said shouldered apertures being Vof a size to permit free passage or' the pro` jection on the lcorrespondinov journal box in another position or saidD journal box transversely of its corresponding Side frame.
